01 - Combine cream cheese, sour cream, cheddar cheese, green onions, bell pepper, spinach, garlic powder, black pepper, and salt in a medium bowl. Mix until smooth and well blended.
02 - Lay tortillas on a flat surface. Spread an even layer of cream cheese mixture over each tortilla, leaving a 1/2-inch border around edges.
03 - Tightly roll up each tortilla from one edge to form a log shape.
04 - Wrap each rolled tortilla in plastic wrap. Refrigerate for at least 1 hour for easier slicing.
05 - Unwrap the tortillas and use a sharp knife to cut each roll into 6 pinwheels, about 1 inch thick.
06 - Arrange pinwheels on a platter and sprinkle with chopped parsley if desired. Serve chilled.
